CONDUlT-RECEPTACLE.

Patented July 17', 1906.

Application led October 25,1905. Serial No. 284,305.

To all whom it may concern.-

Be it known that I, FRANK T. WHEELER, a citizen of the United States,and a resident of Plainville, in the county of Hartford and State ofConnecticut, (whose post-oHice address is Plainville, Connecticut,) haveinvented certain new and useful Improvements in Conduit-Receptacles, ofwhich the following is a full, clear, and exact description, whereby anyone skilled in the art may make and use the same.

The invention relates primarily to receptacles or perha s more properlysockets-that is, a receptac e contaming contact members arranged toconnect an electric circuit through any device by insertin within thereceptacle a plu -like member aving suitable contacts an conductors.

It relates more particularly to what is klnown in the art as awaterproof receptac e.

The objects ofthe invention are to rovide an insulating-receptaclehaving a sma l number of parts and with each of the various parts soassociated and united as to produce a structure which will withstandgreat strains and hard usage -without liability` of disarrangement. i

A still further object is to arrange the contact parts of the receptaclein such manner that the attached conductors may be intimately andositively united with the contact parts belore final assembly.

A still further ob'ect is to provide a receptacle ada ted for con uituse.

Referring to the dra ngs, Figures l, 2, 3, and 4 show in detailed rticalsection the several parts unassembled. Fig. 5 is a central sectionalview with the p ts assembled. Fig. 6 is a detail plan view of einsulating cup or receptacle.

t has been the common practice to use a Shell of insulating material,molded netherwise intimately united with a shell-like contact memberforming one terminal of the circuit and a central contact memberproviding the terminal of opposite polarity. Ordinarily in suchstructures the central contact and the tubular or shell-like contacthave been independent one of the other.

It is one of the purposes of the present invention to combine the outeror shell-like contact and the central contact in a single structure, towhich the conductors ma be rmly and positively applied, as by so dering,rovidmg, of course, a suitable insulation etween the two contactmembers.

In the accompanying drawings the numeral 1 denotes a base of insulatingmaterial having an upwardly-extending tubular or- 6o tion 2 and integrallugs 3, by which the ase or receptacle as a whole may be secured inplace.

On diametrically opposite sides on the base 1 are openings 4 and 5,through which 65 the conductors attached to the contact members(hereinafter described) are led out. It will be noted' that theseconductors roject outwardly from the base 1 at a consi erablc distanceabove its point of attachment, 7o whereby insulation of said conductorsfrom a metallic or other conducting-support is insured.

Within the insulator 1 and at some little distance above the bottom ofits central bore is formed -`the ledge 6, which forms a sto and sup ortfor the tubular contact mem'er 7 wit its contained central contact. Oneof the outletassages, as 4, is formed through the wall o this ledge, andas the parts, are 8o brought together a space 8 is left between thebottom of the bore of the receptacle 1 and the contactfshell 7. Anopening 9 is provided through the bottom of the base to its g centralbore, through which ,a ,suitableinsu....8 lating material ma be ilowedto fill thespaceM 8 an lnsure perfect insulation of the enter-.Qlgnglllmersand-conneetedcontactsn e contact-shell 7, as herein shown,consists of a'screw-threaded shell, though this 9o form may be varied tosuit the exigcncies of any particular case, and a straight plug orscrew-threaded luv may be used by varying the form of the slliell 7.

In the lower edge of the shell is secured a 95 button of insulatingmaterial 10, recessed at its center, as at l l, to receive the centralcontact-stud 12. As shown in cross-section, this insulating-button issubstantially in the form of a half-oval and on its bottom has a recessroo 13 for purposes hereinafter defined. This insulating-button isinserted in the end of the tubular member 7, and the lower edge of thetulle is then spun over the bottom ofthe button, thereby uniting it andholding it iirml in place on the bottom of the contact-Shel The centralcontact-button 12 is of a suitable form to enter the opening 11 and hasa head 14 and stud 15, Which give it a rm bearing in the button 10. Ithas a central bore 16, into which may be introduced the end of theconductor 10, preferably held therein by soldering, and as the solder isflowed into the recess 13, formed about the opening 11, said solder willnot only firmly umte the conductor and contact 12, but forming a spruein the recess 13 will prevent disengagement of the button 10 and contact12.

The second conductor is soldered to the shell 7, and thus all solderingoperations may be performed While the shell, with its containedinsulatin -button 10 and central contact 12, is pulle out of thereceptacle 1.

By pulling upon the conductors after they have been passed through theopenings 4 and 5 the contact members Will be firmly seated upon theledge 6 Within the receptacle, and thereupon the insulating materialintroduced through the openin 9 and filling the recess 8 Will securelyholt? the parts and insulate them perfectly.

Obviously various forms of receptacle and' contact members might beused, and the device might be materially changed as to detail withoutdeparting Jfrom the spirit or intent of the invention.

at I claim as my invention, and desire to secure by Letters Patent, is

1. In combination with a base of insulating material, a tubular contactmember having secured in one end an insulating-button of convex formwith a concave recess in its lower side and a central contact memberiitting within said button and having a part projectin therethrough andinto the concave recess, su )stantially as described.

2. In combination in a receptacle, a base of insulating material havinga central bore,a

ledge formed on the inner wall of said bore,

conductor-openings passing through the walls of the receptacle below theledge, and contact members supported by the ledge 1Wilth one contactmember resting upon the e ge.

3. In combination in a receptacle, a base of insulating material havinga central bore, a ledge formed on the inner wall of said bore,conductor-openings passing through the Walls of the receptacle below theledge, a contact member resting upon the ledge, a coperating contactsupported by the first-named contact member and means for introducing aninsulatin material though the bottom of the receptac e.

4. In a receptacle, in combination with a tubular and central contact, abase of insulating material surroundingsaid parts and provided with aledge or sto forming a seat for said parts with a recess eloW the ledge,conductor-o enings Walls of the ase of insulating material below theledge, and insulating material filling the recess.

' 5. In combination in a receptacle, a base of insulating materialprovided with an internal stop, -tubular contact member located withinsaid baseand seatdupon the stop, having secured thereto aninsulatingbutton With an opening therethrough, a central ggntact memberfitted Within the upper side of said opening, having a tube extendintherethrough to receive `conductor and means for uniting the condlt-or'and central contact and simultaneously locking the contact and theinsulating-button.

6. In combination in a receptacle, a tubular contact member having abottom of insulatin said ottom, a recess formed about saidcontact-opening on one side of the insulatingbottomto retain a mass ofsolder, a contact having a part adapted to project through thecontact-opening into the recess and means including the solder and aconductor for firmly uniting the contact and insulatingbottom.

7. In combination in a receptacle, a base of insulating material havinga central bore, a ledge or stop formed on the inner Wall of said bore,conductor-openin s passin through the Walls of the receptac e below t eledge, a contact member resting on the ledge and forming a support for acoperating contact member and the coperating contact member.

8. In combination in a receptacle, a base of insulating material havinga central bore, a ledge or stop formed on the mner Wall of said bore,conductor-,openin s passin through the walls of the receptac e below t eledge, a contact 'member resting on the ledge and forming a support fora coperating contact member and an insulating-button surrounding saidcoperating contact member.
